To aZZ whom; 2'1? may concern: ,j Be it known that I, RAPHAEL Ilmsnn, :1 viiize'n of the Gernmn'Exnpire, residing at; Han

over, in the Kingdomof Prussia, Germany, have invented certnin'new and hoof-n1 in] provements in Envelope incapable of Being Opened Without Detection, fnlly'seiforth in The following description, and rcprcsentelliin the accompanying drawing.

Envelope in'common use are capable of he'- ingest'sily opened by unauthorized persons,

their contents removed or tampered with, rind their flaps closed and sealed so that it is impossible or difncult to detect the fraud;

This invention has for its object to protect the'contenis of envelope by making itimpoc Bible to resee'l the. envelopswithont leaving evidence ehat they have been opened :ifter the original sealing, at theeeme time effect iug this in such manner that the contents of the envelop are left uninjured by the protecting'menne. This isecc'ompllshod by making the. envelop 'with'front and back portions of substantially similarshew and size and v gnnfimed fiepsiadapted to be'foldczl over theother portion and censeil to mlhore thereto forming one of said porbns with one orlmorealong its edge. This envelopfafziairheing sealed, is pnnehed with perforationgor a line thereof along said gsealed flop orfieps, at or new the edge or edges, thereby ew'oiding injury tothe contents of the: envelop, and in corresponrhn such a'nenner that the three thicknesses of paper, nemebgihe flop, the front,end the back of the envelopmre completely perforated with holes or series 10f the latter;

' In praloticeih is impossible after an unsceling of such a sealed and puncheli flop to replace the three thicknesses and resonl the fie in such-manner: note leave all of them: one holes in the various thicknesses. in exnot'eor respondenee with onch cthfen. j'lhe perfore tio'ne' being entirely through theenvelop rcn darn it easy to detect any x'nrience'from such correspondence or nlinemont of the holes.-

In order to make my in volition more clearly understomL-I have shown .in'fihe accompany- "ing drawing means For carrying itintoprac-,-
